sparingly by Mr. C. G-. Lamb at Nethy Bridge in June, 1905, but was 

 only described by Frey in 1909 from Finland. The remarkable 

 swelling of the postical vein in the male and the pale halteres dis- 

 tingiiish it. 



When Mr. Verrall wrote the above the female of M. excellens was \inknown, 

 but on September 3rd, 1911, at Nethy Bridge, Col. Yerbviry caught both sexes, 

 and an examination of the female proves that it does not resemble x)allix>es (as 

 suggested by Frey) so much as it does apicalis, differing from the former in its 

 larger size, postical cross-vein nearer the wing-margin, and abdomen not so 

 metallic coloiu-ed ; from ajpicalis it appears to differ chiefly in having a white 

 post-ocular ciliation, and knees more narrowly pale. The colouration of the 

 legs, however, varies, the majority having the four posterior tibiae and 3 — 4 

 basal joints of tarsi yellowish, with indications of a brownish ring at base and 

 tip of tibise, but the hind legs are always slightly darker than the middle legs 

 and occasionally tlie hind legs, except the knees, are entirely darkened, and 



the middle legs very extensively darkened. The postical vein is simple. —

56. Telmaturgus tumidulus, Radd. : Col. Yerbury found this 

 species about the margins of a pond on Rempstone Heath in Dorset- 

 shire in August, 1909, and upon a visit there Mr. Collin took a fair 

 number of specimens. The genus Telmaturgus is closely allied to 

 Sympycnus and Syntonuon, but the male is distinguished by the eyes 

 being touching almost all down the face and by the knobbed arista, 

 while the females have the face prodiiced as in Synarthrns, but have 

 the arista placed nearer the base of the third antennal joint ; and in 

 neither sex is the second joint of the antennae pushed thumblike into 

 the third. 



57. Campsicnemus compeditus, Lw : A male of this remarkable 

 species — almost as remarkable as G. matjius — was taken by Col. Yerbury 

 at Studland, Dorset, on June 9th, 1907. G. tnagius is not uncommon 

 on black mud on the east coast. 



58. G. manjinatus, Lw : Dr. J. H. Wood has sent me three 

 males of this well-marked species, which were taken at " Churchyard 

 Dingle," June 22nd, 1908 ; Monnow, July 30th, 1908 ; and Moseley 

 Mere, September 19th, 1910. It is recorded from Germany and Austria, 

 but apparently not since nearly fifty years ago. 



59. Teuchophonis calcaratus, Macq. : I anticipated as far back as 

 1876 that this species woidd occur in England, and Dr. J. H. Wood 

 found it in the Monnow Valley, Herefordshire, while I have taken it, 

 not at all uncommonly, in company with all the other species of the 

 genus, except T. simplex (which occurs within a mile), at Snailwell 

 near here.
